"1.0m i ffm-'y concern.'

e nl known thaty I, inem/nen M. BATES, a eiiixen of the United States, residing at .,..ii-ii .in the county of Cuyahoga and Ohio, have invented a certain new were.: Improvement in Valve-Bags, of which the feiiowing is a specification.

My invention relates to valve bags and has for its object to provide a ba which is temporarily closed at one end en provided with a valve at or near the other.

illy invention is illustrated in the accompaf' i'iying drawings wherein Figure 1 is a sido view of a valve bag with parts broken away, F' 2 is a view of the` same with the open en tied.

Like parts are indioat d by the same letter in all the figures.

A is the material and AA are the sides of the bag, B the valve. made in any. desireel manner and of any desired material.

C is the lower finished edge'of the open end o' the bag. D is the string by which this iower yend 1s temporarily closed when the bag is completed.

in some cases 1t is desirable to have a valve a valve heg which is capable of use either as hagor as the usual open mouth bag. At the same timeitis desirable to have valve bags which are ca able of being opened Without injury to the i ag for the u se of emptying the contents. Many va ve ags, such as the little cheap bags which are used for salt and A other materials, are destroyed by the consumer of the material within the bag.

' "the ease of larger and more valnablebags and where the material is valuable, it is not uncommon for the consumer to open the valve heg With such care that it is uninjured and can be again sewed up and can be used as a valve bag. It often happens-however, as

for exaniiiile in the esse of cement bags, that l return sueh bags for refilling.

the bag is large and relativelyivaluable-Whle theeonsunereis a disinterestedl workman.

If he has ,any difiioulty in opening the bag he is likely to tear it open or out it open so as to make it valueless, Whereas the meet these requirements by oonstructing the ba which is in its completed form, as an'inwar y opening valve at one end and' is temrorarilysecured at the other. Suche bag can Abigjilled `through' a valve in the .usual manner `with raotice is to valve bags, and when the workman receives it he can open it in the most eas and convenient manner byl jerking the st loose or cutting it. The' contents then fa out at sueh opened 4end and the bag 'is' uninjured. It is returnedto the filling factory where the end is tied up to make a complete ba and it is thenV lled 'through the valve. this mamier the danger of having thebags destroyed is obviated no, matter how bareless, indifferent or reckless theworkman using the bags may be.

I claim: i

. 1. A bag having a filling opening'with an inwardly opening valve to Vclose thesame and a temorarily secureddiseharge opening.
